Method and apparatus for operating configured grant timers in wireless communication system

A user equipment (UE), comprising:

• at least one processor;
• and
• at least one non-transitory computer-readable medium coupled to the at least one processor and storing one or more computer-executable instructions that, when executed by the at least one processor, cause the UE to:
• determine whether a first Hybrid Automatic Repeat Request (HARQ) process of a first Physical Uplink Shared Channel (PUSCH) duration of a first configured uplink grant is occupied by a dynamic uplink grant indicating a second PUSCH duration;
• and
• in response to determining that the first HARQ process of the first PUSCH duration is occupied by the dynamic uplink grant indicating the second PUSCH duration:
• determine whether the first PUSCH duration is prioritized over the second PUSCH duration based on a set of rules for determining priorities for the first PUSCH duration and the second PUSCH duration, and
• in response to determining that the first PUSCH duration is prioritized over the second PUSCH duration, perform a transmission on the first PUSCH duration, and start or restart a first configured grant timer corresponding to the first HARQ process of the first PUSCH duration during the first PUSCH duration.
